Nixpkgs 25.05: Package Updates, Removals, and Notable Changes (Part 9)

functionality is deprecated by upstream and causes UI assets not being served after weeks of runtime. - `nq` was updated to 1.0, which renames the `fq` and `tq` utilities to `nqtail` and `nqterm` respectively. - `zf` was updated to 0.10.2, which includes breaking changes from the [0.10.0 release](https://github.com/natecraddock/zf/releases/tag/0.10.0). `zf` no longer does Unicode normalization of the input and no longer supports terminal escape sequences in the `ZF_PROMPT` environment variable. - `confluent-cli` was updated from 3.60.0 to 4.16.0, which includes several breaking changes as detailed in [Confluent's release notes](https://docs.confluent.io/confluent-cli/current/release-notes.html). - `siduck76-st` has been renamed to `st-snazzy`, like the project's [flake](https://github.com/siduck/st/blob/main/flake.nix). - `python3Packages.jax` now directly depends on `python3Packages.jaxlib`. As a result, packages that depend on jax no longer need to include jaxlib to their dependencies. There is also a breaking change in the handling of CUDA. Instead of using a CUDA compatible jaxlib as before, you can use plugins like `python3Packages.jax-cuda12-plugin`. - Added `allowVariants` to gate availability of package sets like `pkgsLLVM`, `pkgsMusl`, `pkgsZig`, etc. This was done in an effort to decrease evaluation times by limiting the number of instances of nixpkgs to evaluate. The option will be removed in the future as a new mechanism is in the works for handling cross compilation.  ## Other Notable Changes {#sec-nixpkgs-release-25.05-notable-changes} - `i18n` module improvements: - `i18n.extraLocales` should now be the preferred way to install additional locales. - `i18n.supportedLocales` is now considered an implementation detail and will be hidden from the documentation. But the option will still continue to work. - `i18n.supportedLocales` will now trigger a warning when it omits any locale set in `i18n.defaultLocale`, `i18n.extraLocales` or `i18n.extraLocaleSettings`. - The options `i18n.defaultCharset` & `i18n.localeCharsets` were added, and they complement `i18n.defaultLocale` & `i18n.extraLocaleSettings` respectively - allowing to control the character set used per locale setting. - Plasma 5 and Qt 5 based versions of associated software are deprecated in NixOS 25.05, and will be removed in NixOS 25.11. Users are encouraged to upgrade to Plasma 6. - `titaniumenv`, `titanium`, and `titanium-alloy` have been removed due to lack of maintenance in Nixpkgs []{#sec-nixpkgs-release-25.05-incompatibilities-titanium-removed}. - [Cursor](https://cursor.com/) — a vscode-based editor that uses AI to help you write code faster — has been packaged as `cursor`. - `octave` (and `octaveFull`) was updated to version `10.x`. The update broke a few `octavePackages`, and `librsb`. See [the PR's commits](https://github.com/NixOS/nixpkgs/pull/394495/commits) for more details. - androidenv has been improved: - All versions specified in composeAndroidPackages now track the latest. Android packages are automatically updated on unstable, and run the androidenv test suite on every update. - Many androidenv packages are now searchable on [search.nixos.org](https://search.nixos.org). - We now use the latest Google repositories, which should improve aarch64-darwin compatibility. The SDK now additionally evaluates on aarch64-linux, though not all packages are functional. - `dwarf-fortress` audio now works again. Additionally, the `dfhack` and `dwarf-fortress-full` packages are now exposed at toplevel, making it easier to install and play Dwarf Fortress. Note that `dwarf-fortress-full` is the Nixpkgs equivalent of the Dwarf Fortress Lazy Pack. - `gerbera` now has wavpack support. - `buildPythonPackage`, `buildPythonApplication` and the Python building setup hooks now support both `__structuredAttrs = true` and `__structuredAttrs = false`.
